The SATA 6Gb/s Archive HDDs come in 5, 6, and 8TB capacities and offer 1.33TB of storage per platter. These drives are geared for storage over performance and feature a spindle speed of 5,900 RPM. Another key point with these drives is the SMR technology that delivers astounding density. SMR (Shingled Magnetic Recording) overlaps tracks on the platter to produce more storage capacity. Due to SMR architecture there are a few drawbacks, notably in performance and compatibility. There are two flavors of SMR coming to the forefront, drive-managed and software managed. Software-managed products require an associated API or software to allow proper function, but drive-managed offerings handle all SMR processing internally. The Seagate Archive HDD features a drive-managed format that delivers excellent out-of-the box compatibility. The Seagate DiskWizard software allows installation of the massive drives in Windows even without an UEFI BIOS.

QLogic joins NVM Express initiative as NVMe Over Fibre spec emerges

Paul Alcorn | Wed, Dec 3 2014 12:04 PM CST

NVM Express, or NVMe, is an optimized interface designed specifically for non-volatile memories, such as flash. As detailed in our Defining NVMe article, NVMe offers unparalleled performance over the PCIe bus. The NVMe specification lays the groundwork for the base technology, but complementary technologies are entering development to further enhance its capabilities. One particularly promising specification is the NVMe Over Fiber standard. This allows for end-to-end NVMe over Infiniband, Ethernet with RDMA, and Intel's Omni Scale Fabric.

Flash has long been confined inside the server in DAS (Direct Attached Storage) configurations. This keeps the SSD as close to the processor as possible, and eliminates network latency. NVMe Over Fibre offers refined performance by removing the SCSI translation layer, which adds latency when communicating over the network. According to recent surveys, network congestion is the most pressing issue for IT professionals. The NVMe Over Fibre standard will refine communication between clusters, and SSDs can be addressed from remote servers as if the PCIe SSD were plugged directly into the server. Qlogic is one of the leading suppliers of server networking products, and their entrance into the NVM Express consortium will likely speed development and adoption of NVMe Over Fibre as well.

Toshiba launches HK3E2 and HK3R2 enterprise SSDs

Paul Alcorn | Wed, Dec 3 2014 10:36 AM CST

Toshiba has been aggressively pushing further in to the datacenter SSD market. Toshiba is surfing the wave of flash pouring into the datacenter, and they recently posted a 70.5% quarter over quarter jump in Q2 2014. There are other sharks swimming in the same pool, and competition for slots has been tough as Intel, Micron, and Samsung also have very competitive products. Toshiba has a long history with flash, they actually invented it, but they also have an often-overlooked advantage of being the only fab-enabled SSD manufacturer with HDD manufacturing as well. This provides them a complete portfolio in the two backbones of enterprise storage.

PMC scores win with Lenovo ThinkServer SAS partnership

Paul Alcorn | Tue, Nov 25 2014 10:53 AM CST

PMC has announced that Lenovo has selected PMC storage solutions for external connectivity in their ThinkServer product line. Lenovo is offering the Lenovo 8885E by PMC for 12Gb/s SAS applications. The low-profile MD2 form factor 8885E is an HBA that provides eight SAS/SATA ports for connectivity. HBA's are becoming more popular in the datacenter as new architectures arise to leverage scale-out storage and advanced erasure coding. PMC Sierra has been very aggressive on the SAS front and recently captured the goal of providing the most SAS ports on a single card. This has led to a leading position in the market, and PMC has currently shipped more SAS ports than their competitors.

The increased density has the side effect of lower power consumption per port, which resonates well in power-constrained datacenters. PMC has measured 40% lower power consumption than their competitors with the same number of devices connected, which results in a tangible TCO reduction for their customers. As a rough guideline most datacenters spec each watt of power as an incremental cost increase of $2 dollars per year. When deploying thousands of SAS adaptors this can lead to a staggering amount of increased cost if there is a difference of a few watts per port.

ATSC lays out path to 100 TB HDDs by 2025

Paul Alcorn | Tue, Nov 25 2014 10:18 AM CST

The quest for more storage has led to revolutionary breakthroughs in HDD technology. SSDs get the most attention in the storage world, but the incredible technology that goes into HDDs has created some of the most refined precision instruments in history. HDD density has increased 500 million fold since the initial designs were released in 1956. During the recent MMM (Magnetism and Magnetic Materials) Conference the ASTC (Advanced Storage Technology Consortium) laid out the continuing path of progress on the HDD front. Acronyms aside, the demand for more storage has resulted in billions of dollars in investments in new technology, and these new techniques are pushing us forward on the path to 100TB HDDs by 2025.

Qualcomm to challenge Intel with low-cost ARM server chips

Paul Alcorn | Mon, Nov 24 2014 12:53 PM CST

Intel enjoys a 97.8% share of the server CPU market, and with AMD continuing to slide, it hasn't looked like anyone can break Intel's stranglehold. Popular new architectures in the datacenter have brought about customized low-power designs that can handle light-impact workloads. Right-sizing servers to the task at hand lowers cost and eases cooling requirements, and ARM processors have attractive low-power features that have always been an interesting alternative in the datacenter. Some Xeons operate within a TDP envelope of 90 Watts, but many 64-bit ARM designs operate between 10 and 45 Watts. Low cost is also another incentive to use ARM CPUs, but a lack of specialized chips and systems has hampered expansion.

This radical reduction in power consumption has led many enterprise powerhouses, such as Red Hat, to institute development projects to boost software development for 64-bit ARM platforms. Microsoft has even gotten in on the ARM-compatibility act by developing Windows RT. RT has been a failure of sorts, but many consider it to be the gateway to ARM-compatible Windows Server flavors. The expanding ecosystem development to further 64-bit ARM processors in the datacenter has placed the onus on suppliers to step up with competitive ARM offerings. One supplier with considerable heft in the ARM category has remained conspicuously silent on server CPU models, until now.

Intel announces 3D NAND design

Paul Alcorn | Fri, Nov 21 2014 2:55 PM CST

Rob Crooke, the Vice President and General Manager of the NVM (Non-Volatile Memory) Solutions Group at Intel, announced the impending release of 3D NAND at Intel's Investor Meeting. Incidentally, the presentation was running on an Intel 3D NAND SSD to demonstrate the progress Intel has already made in integrating their new 3D NAND into a workable device. The launch was a bit light on technical details of the new 3D NAND, but now that images from the presentation are available we are posting more information.

Intel announces 3D NAND design 01 | TweakTown.com

The first Intel SSD was developed in 1992 and featured a whopping 12MB capacity, and continued die shrinks have led to 128Gb dies. The transition to mainstream Intel SSDs began in 2008, and the initial revisions utilized 2D planar NAND. The continued path of NAND development has led to denser designs that sped adoption by lowering the cost per bit. Samsung released the first 3D NAND product in 2014 with 128Gb of density, and Intel's 3D NAND is slated for release in 2015.

Intel announces 3D NAND design 02 | TweakTown.com

Intel helped pioneer the SSD market, and their continued innovation has led to a huge chunk of SSD data center market share. These statistics reflect the current market share of major industry SSD manufacturers. The chart is incomplete and only lists two competitors with NAND fabrication capability. Intel includes the market share of the WD subsidiary HGST in their overall market share numbers due to the HGST and Intel JDA (Joint Development Agreement). The JDA provides Intel NAND to HGST, and in turn HGST collaborates on engineering and manufactures the SAS SSD products.

Micron and Intel produce NAND together in their IMFT (Intel-Micron Flash Technologies) partnership, and Micron's market share is not listed. Toshiba is another fab-enabled competitor not present on the chart, in spite of their recent increase in market share. Toshiba is aggressively pushing further into the datacenter and has publicly disclosed their intention to capture 30% market share by 2016. SanDisk recently acquired Fusion-IO, so the SanDisk and Fusion-io categories of this chart actually need to be combined to get an accurate picture of their market share. SanDisk, according to IDC data, currently has the second largest market share, and SanDisk is also aggressively moving on several fronts to increase their market share. Samsung already has 3D NAND products shipping, but their market penetration lags behind the other competitors on the chart. Intel notes that in spite of the heated competition, they still control twice as much of the data center market as their nearest competitor.
